A Japanese tweeter posted a series of tweets about the “mystery of the company’s disconnection”, which includes network engineering, cultural differences, and a series of coincidences.

A recently occurred exclusion.
Testimony 1: “Sometimes the internet goes off in the morning.”
Me: Is it a problem with the WiFi going off after the computer goes to sleep?
Testimony 2: “It’s a wired network. The wireless network is fine.”
Me: Wired, only had problems in the morning, so strange. It’s still fine at night.
Testimony 3: “The net breaks down when Little A (the Chinese) comes.”
Me: Or is it the human factor? There must be a mistake somewhere.
So I began to investigate.

This seems to be true: shortly after A goes to work, the machine is not connected to the Internet (about 20 minutes).
I observed A’s behavior after he went to work.
・Enter
Put your bag on the seat.
・Go to the boiling water room to make tea
Return to your seat with your tea.
・Change incoming mail
→ This is when people started to lose Internet access.

The following survey is even more puzzling.
“The internet doesn’t go off when I’m making black tea.”
“It sometimes goes off at noon.”
So the oddity seems to be summed up as follows.
“It only happens when A makes her own tea.”
“But it doesn’t matter if you make black tea.”

A. was very considerate of others, so she suggested, “Why don’t I drink black tea from now on?”
But I was determined to unravel this incredible phenomenon.
So I went in for a second investigation.

Since “water” was involved, I thought it was a wireless problem at first, but the fault was only in the wired system, and the backbone was also wired, and there was no sign of a wire break due to stepping on the cable.
Also, having someone else sit in A’s seat, or even making a cup of tea, using A’s cup and kettle, did not trigger the same problem.

Another thought I had.
The water is boiling from an electric kettle, is there a problem with the circuit? But boiling water by someone other than Little A will not be a problem. Changing the water boiler to make tea didn’t improve the problem either.
Is there some kind of device that Little A is wearing? But even if he wasn’t sitting in his seat, the mere act of placing the kettle of tea on the table could cause problems.
In the process I suddenly noticed something.
(7/12)
A always put her water bottle in the same spot in the corner of the table.
I had a flash of wisdom and turned the cheap tin table over to take a look: the corner of the table had a Hub attached to it with a magnet.
In the end, it was worthless: the Hub was overheating due to the thermal conduction of the tea.

I asked A., “Why did you put the water bottle there?”
“Ah, that piece was a little hot, so I left the kettle there, just to keep it warm.”
.
(9/12)
A. was not using a thermos flask, but a plastic flask that was filled with boiling water.
In order to cool it down slowly, he put it in the corner of the table, which was “somehow” hot.
The reason why the table was hot was because there was a HUB on the opposite side.
Overheating of the HUB due to heat transfer from a kettle filled with boiling water to the kettle.
LAN disconnection

This is how the puzzle is solved.
Both the Chinese and Vietnamese are used to drinking boiled water, and both like to use clear plastic water bottles. So the source of this malfunction can be said to be the country (and culture).
The other element is the discovery of “Hey? The “table corners are a little hot” is interesting in its observation and clever use of maneuvers as a cause of failure.
(11/12)
A Japanese employee had sat at this table before, but he used a highly insulated kettle and did not find the corners of the table warm enough to take advantage of it.
The HUB that caused the disconnection is a 1000M old model that was heated by hot water across the table for 10 minutes and then hung up, indicating that the cooling function is already strained and it’s probably time to retire it.

Someone asked, “Why can’t you keep the line open when making black tea?” The conclusion was that the cups used to make black tea were ordinary cups that were kept close at hand, and that the cups were not flat like a clear plastic kettle, but had a depression at the bottom, so heat transfer was not as intense.
I was tempted to give A a thermos cup, but he said, “You can’t use a metal cup to make tea. It is best to be transparent.” …… is worthy of the tea country, pay attention to ah ……
Chinese netizens said: worthy of being Conan’s country, exquisite ……
Thinking Question: If the plot were adapted to Conan, how many episodes would it take and how many people would die in each episode?
Another blind guess as to whether the plastic jug used by Little A is this one (see picture)
